Ritlecitinib
Ritlecitinib (PF-06651600) is a highly selective, orally active, irreversible covalent JAK3 inhibitor (IC50=33 nM) without inhibitory activity towards JAK1, JAK2, and TYK2 (IC50 >10 μ M) . Ritlecitinib rapidly inactivates the JAK3 kinase, and blocks signaling and downstream STAT phosphorylation mediated by common gamma chain cytokines such as IL-2 and IL-15. Ritlecitinib can inhibit Th1/Th17 cell differentiation and function, and effectively suppress preclinical animal models such as alopecia areata, adjuvant-induced arthritis (AIA), and experimental autoimmune encephalomyelitis (EAE) [1][2][3].
